According to customer's parts, 2 Shenyang HTC3650 with GSK988T CNC system and 1 Baoji VMC850L with GSK218MC CNC system vertical machining center are selected.

The machining center selects four-axis control and is equipped with domestic Yantai four-axis rotary working turntable. The CNC lathe is an eight-station hydraulic turret with a hydraulic three-jaw chuck and a hydraulic tailstock.

Develop a detailed processing plan to ensure the processing quality of parts.

The lathe processing scheme is divided into:

Q

Rough machining uses HTC3650 hydraulic chuck with hydraulic tailstock. Step 1 is to clamp the outer circle of the arbor, roughing the large end face and the flat end face. Step 2 is to clamp the processed large end face and cooperate with the tailstock to process the outer circle of the tool bar.

The finishing process is completed in two sets of HTC3650. The large outer surface of the precision turning guarantees the tolerance of the parts, and the outer circle of the turning lever of the precision turning tool guarantees the roughness and the size and cylindricality of the outer circle.

The milling processing program is divided into:

Step 1 is VMC850L with four axes, manual chuck and manual tail top. The chuck clamps the large end face of the outer circle and processes the four planes of the tool bar. Sequence 2 is for clamping the outer circle of the tool holder, rough machining the large end face and the flat end face.

Step 2 is for VMC850L with four axes and special tooling. Hold the outer circle of the tool holder to machine the large end face.
